Why do amplifiers have high voltage gain?
If you got a microphone that converts soft acoustic waves to audio voltage, the low output must be amplified. For that purpose it is good to have an amplifier with high voltage gain. The same is needed for the output of your CD player befor... Read More »

How to Make a Voltage Amplifier
An operational amplifier, or op amp. contains most of the working parts for a voltage amplifier in an integrated circuit (IC) package. In addition to the op amp, the amplifier circuit needs only a pair of external resistors and a power sour... Read More »

What is Considered High Voltage?
There are many voltages that are considered high voltage. Many feel that high voltage should be labeled for as little as forty volts. DOE states high voltage is six hundred volts or more. You can find more information here: http://www.highv... Read More »
